CHAPTER 12NETWORK MANAGEMENT

Network managers perform two key tasks: (1) designing new networks and network upgrades and (2) managing the day-to-day operation of existing networks. The previous chapters have examined network design, so this chapter focuses on day-to-day network management, discussing the things that must be done to ensure that the network functions properly, although we do discuss some special-purpose equipment designed to improve network performance. Our focus is on the network management organization and the basic functions that a network manager must perform to operate a successful network.
